APPARATUS FOR PRINTING ON STONE.

Specification of Letters Patent.

Application filed July 16, 1906. Serial No. 826.496-

Patented April 9, 1907.

T alt whom it may concern:

Be 1t known that I, RICHARD REIss, a subject of the Emperor of Germany, residing in Berlin, Germany, have invented new and useful Improvements in Apparatus for Printing on Stone, of which the following is the specification.

My invention relates to apparatus which serves, with the aid of a type-carrier, for

transferring letters or chartographic characters directly to a lithographic stone or the like, and has reference more particularly to the method of securing adjustability of the bed supporting the stone or the like.

In t e present case the letters or the like are removably secured in a type-Wheel, which on working is inserted in a carriage in which it is moved up and down, whereby it is inked. The wheelis hereby pressed down upon the stone and im arts the im ression directly to the latter. he type-w eel carriage itself rests with capability of motion in all directions in the lane on longitudinal and transverse slides, by which means the type-wheel can be moved in every direction over the stone. The lithograp'hic stone reposes in a a frame and is adjusted at right angles tothe motion" of the type-carrier. This adjustment device forms the subject of my invention. In order to enable adjustment, the frame on which the stone rests is formed as a double frame. The top frame rocks in bearings in the main framing and can be fixed in the desired osition by suitable devices, so that the s ace of the stone may lie at the most favorable angle for the eye of the lithographer and the light and for ready survey of the field of work. The bottom frame is held to the top frame by adjustment-screws, a suitable number of which pass through the top frame.

One form of construction of thenew apparatus is shown in the accompanying drawings, in which Figure l is a perspective view,,and Fig. 2 a side elevation.

-In the framing A of the machine there rests in bearings A the top frame B ,-which supports the entire chartogr'aphic -printing device on slides. It is held at the angle given to it by a slotted stay C and a pressingscrew C The bottom frame B is suspended below the to frame by means of screw-spindles with and wheels B. The bottom frame B carriesthe stone which is to be The bottom frame B is raised.

exactly into the desired position relatively to the type-wheel.

Having thus described my invention, What I claim is' In combination a main frame, a top frame having its ends journaled therein, a chartographic printing device slidably mounted on said top frame, screw spindles passin through the top frame, hand-wheels secure to the top of said spindles and a bottom frame for the stone supported on the ends of the s indies so that said bottom frame may be a justed by rotating the s indles.

In Witness whereof I have ereunto signed my name, this 9th day of April, 1906, in the presence of two subscribing witnesses.

RICHARD REISS.
